Father Complex. Hazard and Somerset: Arrows in the Hand, #4

Having a father can be hard. Being a good one might be even harder. The call-out for the double homicide, when it comes, is a strange one: two men gunned down in a motel room, no witnesses, no real clues. Even stranger, the men were enemies, and no one seems to know why they were in that motel room together. And stranger still, people won't stop calling John-Henry Somerset, telling him he needs to find some answers-preferably nice, easy ones-fast.
Hazard and Somers set out to learn what happened, but they quickly find themselves mired in shifting factions: the ultraconservative political machine of the Ozark Volunteers; a liberal activist group protesting the local gun show; a reclusive fundamentalist church; even a hint of Mexican drug cartels. The further they press their investigation, the clearer it becomes that the killer-or killers-wants something, and they'll stop at nothing to get it.
As Hazard and Somers struggle to find the truth, they face trouble at home as well. Their foster-son, Colt, has received a letter from his estranged father, the same man who attacked Colt and Somers in their home. Worse, Colt seems open to more communication, which leaves Hazard grappling with his fears for Colt and his helplessness against a world that seems to be conspiring to take his foster-son away.
But when a pair of gunmen come after Hazard at home, two things are crystal clear: he's going to get to the bottom of these murders, and he'll do anything to keep his family together.
